  • Maximum likelihood estimation for multivariate normal samples : theory and methods 
    Strydom, H.F. (Hendrina Fredrika); Crowther, N.A.S. (Nicolaas Andries Sadie), 1944- (South African Statistical Association, 2012)
    Maximum likelihood estimation of parameter structures in the case of multivariate normal samples is considered. The procedure provides a new statistical methodology for maximum likelihood estimation which does not require ...
  • Multivariate normal estimation : the case (n < p) 
    Strydom, Nina; Crowther, N.A.S. (Nicolaas Andries Sadie), 1944- (Taylor and Francis, 2018)
    Estimation in the multivariate context when the number of observations available is less than the number of variables is a classical theoretical problem. In order to ensure estimability, one has to assume certain constraints ...
